Chicory (Cichorium intybus L.) as a Multifunctional Medicinal Plant

Abstract

Cichorium intybus L., commonly known as chicory, is a widely distributed medicinal plant belonging to the Asteraceae family. It has been traditionally used in folk medicine to treat liver, digestive, inflammatory and metabolic disorders. In recent decades, it has attracted considerable scientific attention due to its rich phytochemical composition and exceptionally broad spectrum of biological activities. This review summarises the latest research on the botanical characteristics, phytochemical diversity and pharmacological properties of C. intybus, focusing on its antioxidant, anti-inflammatory, immunomodulatory, antimicrobial, antiviral, antiparasitic, hepatoprotective, antidiabetic, cardioprotective, neuroprotective and antitumour effects. These activities are primarily attributed to polyphenols, flavonoids, phenolic acids, sesquiterpene lactones and inulin, which act synergistically to regulate oxidative stress, inflammatory responses, immune functions and key metabolic pathways. Other minor constituents, such as coumarins, sterols, terpenoids, and volatile compounds, also contribute to the plant’s pharmacological profile. Evidence from in vitro, in vivo and clinical studies suggests that chicory extracts and isolated compounds have significant therapeutic potential in treating various pathological conditions, including diabetes, liver disease, infections, cardiovascular disorders and cancer. Importantly, emerging data also highlight its role in modulating gut health, endothelial function and neuroinflammatory processes, thereby expanding its relevance beyond traditional applications. While the accumulated evidence strongly supports the pharmacological importance of C. intybus, further standardised clinical trials, studies to optimise dosage, and investigations into its mechanisms are required to validate its efficacy, safety, and therapeutic potential in evidence-based medicine.
